abstract = {We propose a new algorithm for the identification of the
production flavor of neutral $D$ mesons in the Belle II
experiment. The algorithm exploits the correlation between
the flavor of a reconstructed neutral $D$ meson (signal $D$
meson) and the electric charges of particles reconstructed
in the rest of the $e^+e^-\to c \bar{c}$ event. These
include those originating from the decay of the other charm
hadron produced in the event, as well as those possibly
produced in association with the signal $D$ meson. We
develop the algorithm using simulation and calibrate it in
data using decay modes that identify the flavor of the
decaying neutral $D$ meson. We use a data sample of $e^+e^-$
collisions, corresponding to $362\,\mathrm{fb}^{-1}$ of
integrated luminosity, collected by Belle II at
center-of-mass energies near the $\Upsilon(4S)$ mass. The
effective tagging efficiency in data is $(47.91 \pm 0.07
\mathrm{(stat)} \pm 0.51 \mathrm{(syst)})\\%$, independent
of the neutral-$D$-meson decay mode. This charm flavor
tagger will approximately double the effective sample size
of many $CP$-violation and charm-mixing measurements that so
far have exclusively relied on neutral $D$ mesons
originating from $D^{*\pm}$ decays. While developed for
Belle II, the basic principles underlying the charm flavor
tagger can be used in other experiments, including those at
hadron colliders.},
